2. The Aging Process

3. What is the aging process? • Aging begins at the time human is born • Living Is a process of continual change • Infants become toddlers, children blossom into young men and women, and dependent adolescents develop into responsible adults • Continuation of change into later life is natural and expected

4. Why do people age? • There are many theories • Genetic and hereditary factors • Loss of cellular mass and ability of cells to divide and replicate • Accumulation of waste materials that clog cells and leads to cell death • Changes in structure of connective tissue (blood)

5. When does the aging begins? • The type, rate, and degree of physical, emotional, psychological, social changes experienced during life are highly individualized • Although some similarities exist aging is a unique process in each person • Aging changes influenced by genetic factors, environment, diet, health, stress, lifestyle choices, and numerous other elements

6. Changes to the body: Physical appearance • After 4th decade of life adults start to experience hair loss • Both sexes develop gray hair and wrinkles • Fat atrophy cause body contours gain bony appearance • Tissue elasticity cause elongated ears, double chin, baggy eyelids • Loss of subcutaneous fats cause older adults to be more sensitive to cold temperature • High decreases for about 2inches by 80 years old • Body shrinks due to reduced hydration, loss of cartilage, thinning of vertebra

7. Changes to the body: Respiratory/Cardiovascular • Since older people can not breathe as fast, there is less oxygen entering the blood per minute. Less oxygen in the system cuts down the amount of work that can be done • Due to decreased mobility respiratory activity reduces gas exchange leading to high risk for developing respiratory infection • Heart losses its efficiency and contractile strength resulting in reduced cardiac output • Blood vessels lose elasticity with age making heart have to pump harder to circulate blood • Less blood pumped results in lowered blood oxygen levels

8. Changes to the body: Gastrointestinal system • Bone that support the teeth decrease in density and height, contributing to tooth loss • Tooth loss lead to dentures wear, which may not be worn regularly because of poor fit and discomfort • Taste sensation become less acute with age affecting taste buds • Excessive seasoning of foods lead to health problems • Slow motility of large intestine causes constipation

9. Changes to the body: Musculoskeletal system • Loss of elasticity of connective tissue can cause pain and impair mobility • No way to prevent these changes • Maintain bone health through diet, exercise and getting adequate rest • Always consider medication side effects when assessing mobility concerns

10. Changes to the body: Vision • Not all older people have impaired vision • Loss of ability to see items that are close up begins in the 40’s • Size of pupil grows smaller with age: focusing becomes less accurate • Lens of eye yellows making it more difficult to see red and green colors • Sensitivity to glare increases • Night vision not as acute

11. Changes to the body: Hearing/Touch • Presbicusis is a progressive hearing loss that occurs as a result of aging • Have trouble hearing over the telephone/ Need to turn up the TV volume • Find it hard to follow conversations when two or more people are talking • Have a problem hearing because of background noise • Sense that others seem to mumble • Equilibrium cab be altered because of degeneration of the vestibular structures • Reduction in tactile sensation • Decreased sensation in pressure, pain, and different temperatures

12. Conclusion • We all change physically, as we grow older • Some systems slow down, while others lose their "fine tuning." • People who live an active lifestyle lose less muscle mass and flexibility as they age • As a general rule, slight, gradual changes are common, and most of these are not problems to the person who experiences them • Steps can be taken to help prevent illness and injury, and which help maximize the older person's independence, if problems do occur • There is no need for most people to fear getting older
